An infant and a child were rushed to an area hospital. The infant, 10-month-old Aiden Lawson, was pronounced dead at the hospital. The other child, a 3-year-old girl, remains hospitalized. She suffered from smoke inhalation and family friends say she is expected to survive. They say she will be living with relatives when she is released from the hospital.
